ABSTRACT: Waste and industrial by-products represent a significant
percentage of the industrial landfill. The evaluation of these products has a
dual effect: it avoids both the landfill (risk of environmental pollution) and
limits the use of natural aggregates (depletion of natural resources and
landscape fragmentation and the imbalance of the ecosystem). In recent years,
applications for industrial waste have been taken into account in the
construction of roads with a great interest in many industrialized countries
and developing countries. The use of these materials in the construction of the
road is a decision based on technical, economic and ecological criteria. In Algeria, the steel plant of El-Hadjar (Annaba), due to its
activity generates a significant industrial waste (slag) which creates a
storage problem and pollution. For industrialized countries, this product is an
abundant raw material at low cost that must be used on a large scale public
works. Our study implies the use of slag in the preparation of the subgrade and
surface course (as coated). The results of chemical, physical and mechanical
analyses of El-Hadjar slag and materials developed, compared to those of natural
aggregates, can be used as aggregate in road construction.
